AA post capitalization

We had an asset that was created last year and was posted depreciation with the wrong depreciation key. This yr in march the depreciation key was changed.

To correct the asset instead of posting unplanned depreciation or opening yr 2006 they have used post capitalization for the asset and also did a depreciation run.

Is there a way to correct this as the asset has depreciation posted already in the previous asset until march of this year.And again the entire depreciation has been posted this year with the correct depreciation key in a new asset created by post capitalization. I can not tell them to reverse the asset as they already did a depr run.

How should I correct this situation. Any clarification will be appreciated.

Thank you
